Thanks for your comments. It seems that there were no objections to most of the points I made.
So, we are in agreement, and I would like to put into evidence the following facts on 1st Century Jerusalem:
1. Jerusalem was primarily Jewish in the 1st half of the 1st century. The people lived by the Jewish religion and Jewish customs.
2. The population of Jerusalem was 97% illiterate. The vast majority did not know how to read or write.
There was some objection to the third point I was trying to make
3. Education was transmitted orally
I do not feel anyone denied that, however there was discussion to the reliability of oral transmission and the fact the message could be changed over a period of time.
